Modular Belts - Introduction

Modular belt, Radius flush grid, curve-runningThe belt consists of plastic hinged links connected by plastic rods. The wide belts are woven together by links that are 102 mm, 124 mm, and 180 mm wide. The assembled belt forms a wide, flat, and tight conveyor sur-face. Five standard widths of belt can be delivered: 152 mm, 203 mm, 304 mm, 456 mm, and 608 mm.

Standard belt color is white but blue belts can also be ordered.

Belts with polyamide pins are available for dry or semi-wet applications. In constant wet applications, belts with acetal pins must be used. This is due to the fact that pol-yamide pins will absorb water and swell in wet applica-tions, and acetal pins will squeak in dry environments.

Flat top belt, straight runningThe belt has a minimal number of seams and has open hinges that are easy to clean. The belt is white and is available with acetal pins for wet applications

Travel direction of the belts:

Radius flush grid Flat top belt

Technical characteristics

Tools and accessoriesThe belt should be pretensioned with a return slack of about 25 mm. Too much belt slack is a safety risk as the belt can hang below the side of the conveyor beam. A belt tensioner tool (5118803) is available in order to facilitate installation of the belt and minimize the amount of slack in the return belt.

Ordering information The belt is delivered in assembled 1 m lengths. To calcu-late the total length required, remember to add for belt consumed by the idler and drive units.

Conveyor Beams - Introduction

Frame profiles and cross barsIn order to facilitate cleaning, the top belt can be lifted up and the outer slide rails can be folded back.

For hygiene reasons, the WLX system is based on an easy-to-clean, free hanging return belt.

Elongation of the belt due to load is normally evenly distributed on the return side and along the whole con-veyor, and placement of the belt guides for the return belt is critically important for proper conveyor system perfor-mance. Conveyor beams can be ordered from 142 mm up to 3000 mm and are always pre-engineered and con-figured according to the rules that must be followed.

Conveyor beams are normally not symmetrical, which is why they have an upstream and downstream end. An arrow label on the conveyor beam side indicates the appropriate top belt travel direction to ensure correct assembly.

Components such as plain bends, etc., cannot be placed too close to an End drive unit. Therefore, the min-imum permissible length for conveyor beam sections

when connecting to an End drive unit is 844 mm. This ensures a sufficient amount of return belt tension directly after the drive sprocket to avoid slack close to the sprocket wheel. The return belt hanging between the first two belt guides provides this belt tension (called back tension). For more information see WLX Engineering guidelines.

Connecting brackets have to be ordered separately when joining End drives, idler ends, conveyor beams, etc.

When joining two conveyor beams, a beam spacer kit must be ordered separately.

End Drive Units - Introduction

End drive units

Drive unit typesA soft motor start is recommended for use with high-speed and long conveyors. This is because these types of modular belts are quite heavy, and the free hanging return belt can begin to oscillate momentarily during startup.

A grease nipple is included in all flange bearings. The bearings are initially filled with FDA-approved, food-grade grease (NSF H1).

End drive units including SEW motors IP 65, can be ordered with food-grade oil and stainless steel hollow shafts in the web-based configurator.

Motor specificationsMotors are available for 230/400 V, 50 Hz and 230/460 V or 330/575 V, 60 Hz. All motors can be connected for delta or star configuration by means of jumpers.

Variable speed motors are SEW Movimot, 380–500 V. Note that variable speed motors include a control box that adds 93 mm to the width of the motor.

Technical specificationsMaximal speed................................... 40 m/minNumber of teeth on sprocket wheel ... 2×16

Belt tensioner unitA belt tensioner unit should always be placed near the End drive unit and its use is recommended:

- for long conveyors >20 meters

- for long conveyors >15 m and a speed of >30 m/min

- for conveyors with frequent starts/stops, especially if the load is high

- if an End drive unit needs to be placed close to a plain bend

- if an End drive unit needs to be placed on the lower part next to a conveyor slope section

- for short conveyors where the belt slack length is insuf-ficient to lift the belt for cleaning

Ordering informationDrive units with motors must be specified using the web-based configurator. The configurator provides detailed information and step-by-step guidance in the specifica-tion process. A product code string is generated, contain-ing the specification details. See next page for examples of code strings.

Drive units without motors can be ordered using the des-ignations in the catalogue.

• Connecting brackets have to be ordered separately.

• Slide rail must be ordered separately.

Dimension drawings in catalogueNote that dimensions relating to drive unit motors depend on the motor specified during the configuration. In most cases, the motors shown in the catalogue drawings rep-resent the largest size. If variable speed motors are used, some dimensions may increase, indicated by dimension values xxx (V: yyy). V represents the max dimension using variable speed motor.

Idler end units – Introduction

Chain guidance at end of conveyorThe idler end unit is used to guide the chain from the return side of the conveyor up to the top side with a min-imum of friction. The chain is guided by two or more idler wheels on a common, rotating shaft supported by ball bearings.

Ordering information• Connecting strips are included with the idler end

units.

• Slide rail must be ordered separately.

Plain Bends - Introduction

When using radius flush grid belts in plain bends, the belt pull force will be concentrated on the outer part of the belt. A certain straight section is needed before and after the bend in order to transfer the load between the outer belt section and evenly distribute it to the straight belt section. This is critical before entering another plain bend, end drive unit, etc. This required straight section is always integrated in the plain bend itself (300 mm for WL374X, 450 mm for WL526X, and 600 mm for WL678X).

Plain bend placement, as for all other Flexlink conveyors, should always be considered. A plain bend placed too far downstream on a conveyor generates unnecessary belt pull. Also, placement of a plain bend too close to an end drive unit can lead to an unnecessary slack increase and a separate slack unit must be added. Always use the Flexlink calculation tool (FLCT) to calculate the resulting pull forces.
